Hierarchical steepness, defined as status asymmetries among conspecifics living in the same group, is not only used as a main characteristic of animal social relationships, but also represents the degree of discrepancy between supply and demand within the framework of biological market theory. During September and December 2011, we studied hierarchical steepness by comparing variation in grooming patterns in two groups of Tibetan macaques (Macaca thibetana), a primate species characterized by a linear dominance hierarchy. Using a focal sampling method, we collected behavioral data from two provisioned, free-ranging groups (YA1 and YA2) at Mt. Huangshan, China. We found that female dominance hierarchies were steeper in the YA1 group (0.81 based on the proportion of wins-losses and 0.66 based on dyadic dominance indices) than among members of the YA2 group (0.76 based on the proportion of wins-losses and 0.56 based on dyadic dominance indices). Females in the YA1 group groomed more frequently and for longer duration than females in YA2. Further analysis showed that grooming patterns of high- and low-ranking females did not differ between the two groups. However, middle-ranking females in YA1 groomed conspecifics more frequently and for longer duration than middle-ranking females in YA2. Our results suggest that the steepness of a dominance hierarchy plays an important role in the set of social strategies used by middle-ranking females to avoid a reduction in rank, as well as to increase their rank (the dilemma of middle class hypothesis). We suggest that future studies focus on individuals of middle-rank in order to better understand how the dynamics of rank stability and rank changes influence social relationships, and affiliative and competitive interactions in non-human primates.

Narcissistic Personality

AbstractNarcissistic Personality Disorder is characterised by inflated self-importance, an excessive need for admiration, and a lack of empathy. The interpersonal difficulties associated with narcissistic personality may be becoming more widespread given its increasing prevalence within the general population. This systematic review investigated the relationship between narcissistic personality traits and social cognition (i.e. theory of mind; emotion recognition; empathy; emotional intelligence) in clinical and non-clinical samples. Cognitive empathy (i.e. perspective taking) appears unlikely to be impaired, while affective empathy (relating to another’s emotion state) may be reduced in association with narcissism. Those with grandiose narcissism rate their empathic skills more highly than those with vulnerable narcissism, but concurrent administration of objective measures is rare, limiting insight into the validity of self-ratings. Rather than deficits in aspects of social cognition, the overall pattern could reflect motivation, or advantageous use of social cognitive skills to serve the self. Indeed, interpersonal strategies associated with narcissism (e.g. deception; manipulation) suggest the application of understanding another’s beliefs or desires in the context of low empathy. Further research should seek to explore performance on a wider range of emotion recognition and theory of mind tasks, and whether characteristics such as excessive jealousy and paranoia could reflect hyper-mentalizing.

The Individual

Male nonhuman primate sexual interference, which includes copulation interruption and copulation harassment, has been related to reproductive success, but its significance has been challenging to test. Copulation interruption results in the termination of a copulation before ejaculation, whereas copulation harassment does not. We conducted this study using the all-occurrence behavior sampling method on sexual interference behaviors of seven adult and four subadult male Tibetan macaques (Macaca thibetana) in mating and non-mating seasons at Mt. Huangshan, China, from August 2016 to May 2017. Our results showed that males’ individual proportion of copulation interruption and harassment was higher during the mating season than during the non-mating season. In addition, dominant males more often performed interruption, whereas subordinate males more often performed harassment. We found no difference in the individual proportion of copulation interruption or harassment between adult and subadult males. Adult and subadult males both directed copulation interruption and harassment more often toward the mating male than toward the mating female. Lastly, the post-ejaculation phase of copulation was shorter when copulation harassment occurred than when it did not. Our results suggest that sexual interference may be an important mating tactic that adult and subadult males use in male–male sexual competition.

This article focuses on the changes that occurred within Querétaro's elite from the late Habsburg to the high Bourbon period in colonial Mexico from the perspective of its relationship to the convent of Santa Clara. It explores how creole elite families of landed background with firm roots in the early seventeenth century, tied together through marriage, entrepreneurship and membership in Santa Clara were slowly pushed out of the city's economic and administrative circles by a new Bourbon elite which broke with the social strategies of the past by not sheltering its daughters in the city's most opulent convent.

Social Behaviours

One of the most striking facts about parasites and microbial pathogens that has emerged in the fields of social evolution and disease ecology in the past few decades is that these simple organisms have complex social lives, indulging in a variety of cooperative, communicative and coordinated behaviours. These organisms have provided elegant experimental tests of the importance of relatedness, kin discrimination, cooperation and competition, in driving the evolution of social strategies. Here, we briefly review the social behaviours of parasites and microbial pathogens, including their contributions to virulence, and outline how inclusive fitness theory has helped to explain their evolution. We then take a mechanistically inspired ‘bottom-up’ approach, discussing how key aspects of the ways in which parasites and pathogens exploit hosts, namely public goods, mobile elements, phenotypic plasticity, spatial structure and multi-species interactions, contribute to the emergent properties of virulence and transmission. We argue that unravelling the complexities of within-host ecology is interesting in its own right, and also needs to be better incorporated into theoretical evolution studies if social behaviours are to be understood and used to control the spread and severity of infectious diseases.
